Distinguish between AcquireExternalFD and epoll_create1 / kqueue failing The error messages in CreateWaitEventSet() made it hard to know whether the syscall or AcquireExternalFD() failed. This is particularly relevant because AcquireExternalFD() imposes a lower limit than what would cause syscalls fail with EMFILE.
I did not change the message in libpqsrv_connect_prepare(), which is the one other use of AcquireExternalFD() in our codebase, as the error message already is less ambiguous.
